Claims16
A method of connecting a heat exchanger apparatus to a tank,
- said heat exchanger apparatus comprising a flange and at least one heat transfer tube directly mounted on a first surface of the flange, opposing ends of each heat transfer tube arranged in fluid communication with a corresponding intake port and exit port extending through the flange, and
- said tank comprising a tank flange having an opening formed in a surface of said tank to an outside of said tank, the tank flange having approximately a same diameter as the flange of said heat exchanger apparatus,
- said method comprising,
- aligning the heat transfer tube such that the heat transfer tube extends inside said tank through the opening formed in the tank flange,
- mounting the first surface of the flange of the heat exchanger against the tank flange, and
- attaching the first surface of the flange of the heat exchanger to an outside surface of the tank flange, wherein
- the at least one heat transfer tube is configured to be in direct contact with material stored in said tank, and
- said heat exchanger apparatus is configured to be removable from said tank.
